Bloody hell, this is STILL going on.... It must be at least 8 or 9 years ago LR Tech support told me the "Pressure signal constantly high" fault was a failing drive pack if the pressure switch checked out OK.
There were some faulty pressure switches,I cant think that any of them are still around or in use.Back when I was given the tip I was very suspicious as I couldn't see how it could be right.But I was in trouble with loads of the things faulting all over Europe with irate owners - and not getting to the bottom of the problem.Changing a few drive packs - I even remember the part number,ANR3900 ? made the problem go away.
I could never be bothered to work out why it happened,and I seem to remember asking certain members on here to accept the challenge and tell us all...

Yep remember that. Still say look at the pressure switch first before splashing out on a driver pack. Keith is going to tell us why it happens cause i ain't got a fooking clue. :D:D

Like I said if the pressure switch checks out OK,do the drive pack.The more common fault was a constantly low signal - yet another worn out compressor.Dont do much with P38's now,mostly too old,but by coincidence I ordered a new compressor for one just today.
Recently its more D3/RRS with worn out compressors - WAAAYYYYYYY more expensive rubbish !

Yes it does seem Land rover have employed more economics graduates to do the parts pricing. Possibly based on cost plus 150%, plus 100% stocking charge, plus 200% profit. :D
 
I would assume that failing driver pack cases the EAS System to use too much air trying to correct all the time --> hence pressure switch is open, and the signal is high. Compressor cannot keep up and wears out, --> hence even less air to adjust with.

From EAS Info Document:
PRESSURE SWITCH STUCK ON (CLOSED) OR OFF (OPEN)
These messages are set when the air usage does not correspond to the implied air pressure. Remember that the system has no way of determining the actual air pressure. Perform a Pressure switch test using TestBook and LRT-60-001 pressure gauge to verify switch operation.

No,it was nothing that sensible,I did lots of road testing with faulty vehicles,dataloging,driving with Testbook on live data etc - none of it made sense.I was just grateful for the solution.
Wammers,I think you are being slightly cautious with your parts pricing structure....

Dam and blast quoted the P38 pricing policy, for L322 and on quadruple everything. For anything that breaks on a regular basis double that and for anything that someone may break in five years time threble it. :D

Yeah i am a fair bloke i am. But i still can't get over £76.00 for twelve inches of brake pipe and two tube nuts. Specially when the opposite hand is £36.00 for the same thing bent the other way. A fiver would be to much for either. :D:D

That's a good reason to rip the motorist off then? Anybody who can do the job themselves who takes his car to a garage needs their bumps feeling. :D:D

Yep its quite clear that Tata are interest only in making money with a premium brand,not making four wheel drives that work for a living.
Same as Corus said when they shut down Llanwern steelworks - "We are interested in making money,not making steel." Despite the plant being very efficient in terms of quality and productivity.Here I go getting all cynical and political again...

All Bosel exhausts, who used to make most of the exhausts for Land Rover and others are now made in Europe, Romania and the like. All the machines were lifted from the factory here and shipped out there. Cheap labour, all we have here now where the factory was is a warehouse. Bosel sold the factory site off and rent part of it back as a store/distribution warehouse for the bits they get sent in from various parts of Europe. Britain being part of the EU created jobs for sure, but in Europe, all the jobs here were lost.

Basically it's an electrical noise problem caused within the driver pack spooking the EAS ECU. I have found one cause but there may be others.
 
morning guys, so i have a couple of driver packs now spare..
I'm planning to change one.. and with ( hopefully ) some guidance from Datatek at some point, wanted to take one apart, look and maybe rebuild it ( possible another thread for us on that?)..

however.. just run me over taking the old one off..


1. de-preasurise ( it's ok to do this with out stands ? i.e, just onto the bump stops ?)
2, remove pump
3. jiggle valves around to get access to Driver pack ( do i need to remove the air lines ? i'm worried about damaging them.. and done currently have spare 'O' rings etc for them )
4. disconnect driver pack and re-fit spare..
refit pump,
5. re-pressurise and test

it did do another weird thing this morning where it just decided to go to wade height all on it's own while i was driving alone...

hmmmm

thanks as ever
